Hello! I'm 22 weeks pregnant as of today. Last Sunday I noticed my lower back on my right side was sore and it seemed to go across my stomach. I just thought maybe I moved wring and it would go away. I ended up on the ER on Tuesday because the pain was so horrible, They did an ultra sound and the baby is fine. They also did an u/s on all my other organs and did blood work, Everything came back normal. I was sent home with a prescription for amoxicillan (in case there was an infection that didn't show up) ,told to take tylenol every 4 hous and come back on Thurs. i went back and still couldn;t figure anything out. Anyone have any suggestions so I can get some relief from this pain? This is our 2nd pregnancy. My first one ended in a m/c last summer, so I'm not sure if this is just something that will go away on it's own??? Thank you all for your help!!
